Solar panels need to be clean to generate power effectively. Softwashing is the perfect way to clean them without damaging electrics or roof tiling.
Any man-made or organic residue or film that blocks transmission of sunlight to photovoltaic solar (or thermal) panels can substantially diminish their performance. Less light means less energy, leading to a lower return on a commercial or domestic investment in renewables. Often the offenders are moulds, algae, and bacterial atmospheric growths that can be removed by softwashing. While rainwater is thought to keep solar panels as clean as they need to be , this is not the case. Environmental factors such as salt in seaside locations, or dust and grime from highways and railways, can decrease output dramatically. When monitoring their own vast power usage, Google proved that regular solar panel cleaning can improve panel performance by up to 12%.
While it may seem obvious and simple to clean the panels yourself, tap water when used in isolation is not up to the task, since residues and deposits of salt and minerals on the panels are left behind after tap water treament. Using chemical free pure water these deposits can be eliminated. Old fashioned cleaning methods, like high pressure cleaning, are too violent for the technology, and will damage photovoltaic cells, and reduce the shelf-life and performance of solar panels.
When cleaning solar panels, we use a clearly defined softwashing process which brings these vital technologies back their optimum, using 0% chemicals and only pure water.
We use extendable water fed poles wherever possible, and cherry pickers to avoid needing unnecessary access to the roof.
We use localised soft brushes that offer maximum protection for solar panels.
Softwashing will bring your solar panels back to their peak, returning your investment and keeping them performing for as long as the sun keeps shining.
Solar panels are an excellent investment for homes and businesses across the UK, offering clean, renewable energy. However, over time, panels can become coated with dirt, bird droppings, lichen, moss, and other debris — all of which can reduce their efficiency. That’s where Softwashing UK comes in.
We offer professional solar panel cleaning using specialist soft washing technology — a safer, longer-lasting alternative to abrasive or high-pressure methods.
Specialised Soft Wash Technology
Unlike high-pressure cleaning, which can damage the delicate surface and seals of your solar panels, our low-pressure soft wash system uses pure water and biodegradable cleaning solutions. This method safely removes dirt and organic build-up without scratching or harming your panels.
Longer-Lasting Results
Our soft washing not only restores the appearance of your solar panels — it helps maintain their performance. By removing contaminants that block sunlight, we help your panels operate more efficiently, meaning better energy output and reduced electricity bills.
Moss, Lichen & Algae Control
We don’t just clean — we treat. Our softwash solution includes a biocidal component that kills moss, algae, and lichen at the root, preventing regrowth and ensuring your panels stay cleaner for longer.
Gentle on Surfaces, Tough on Grime
Our gentle cleaning process protects the integrity of your solar panels while being tough on grime. It lifts away years of environmental build-up without compromising any protective coatings or fixtures.
